Zombie skinks

I just purchased some VC models and I have decided that I will fill my zombie ranks with models from other armies. I want to paint some skinks so that they could be either zombie skinks or be used as part of my lizardmen army.

What would you guys recommend for the paint job to make them look like zombies. My color scheme will most likely be white flesh (that would match my other skinks). I guess I could paint them so that muscle fiber is showwing on their bodies. Maybe replace a couple of arms with ghoul arms or skeleton arms.

pale patchy skin, maybe with some sickly green and pink bits...
there used to be a skelital Regiments of the Renown unit
with skeletons from various races, including Lizardmen,
migth be worth geting if you ever run across it.
